The invention discloses a PLC-based mining explosion-proof intrinsic safety type programmable control box, which comprises a fixed seat, a breather pipe, a connecting frame, a protective shell and a liquid conveying pump, and is characterized in that a control box main body is arranged at the upper end of the fixed seat, a controller is arranged in the control box main body, and the outer side of the control box main body is connected with a connecting shell; the protective shell is arranged on the outer sides of the connecting shells on the left side and the right side, second cooling fins are arranged on the side face of the protective shell, one ends of the second cooling fins are arranged in the cooling water tank in a penetrating mode, the cooling water tank is arranged in the protective shell, the liquid conveying pump is arranged in the cooling water tank, and a temperature sensor is arranged on the cooling water tank in a penetrating mode. According to the mining explosion-proof intrinsic safety type programmable control box based on the PLC, external air flows in the arranged vent pipes and can exchange heat with the interior of the control box main body, heat dissipation in the control box main body is enhanced, dust and moisture are prevented from entering the control box main body, and under the action of the arranged first cooling fins, the heat exchange area with the interior of the control box main body is increased.
Description
technical field [0001] The invention relates to the related technical field of mining equipment, in particular to a flameproof intrinsically safe programmable control box for mines based on PLC. Background technique [0002] Mine explosion-proof and intrinsically safe programmable control box is suitable for the control device of the equipment in the dangerous environment of gas and coal dust explosion in the coal mine or the harsh environment on the ground. It can be used as a Comprehensive protection devices for production equipment in harsh environments such as factories and power plants. When cooling some mine-used flameproof and intrinsically safe control boxes, they use fans combined with cooling holes to dissipate heat, which can easily cause external dust and moisture to easily enter the interior. It affects the interior, and in the process of moving and transferring, it cannot play a buffering effect and is easily affected by bumps. Now a PLC-based mining flameproof...
